Knowledge management, as a new managerial concept, is the specific embodiment of knowledge based economy in the field of management while technological innovation, constituting the core of technological progress, is the effective extension and application of scientific and technological knowledge. Hospitals, which are knowledge based institutions, possess good foundations and advantages of implementing knowledge management and technological innovation. There is a close link between knowledge management and technological innovation in hospitals, the former being the basis and primary guarantee of the latter and the latter being the result and manifestation of the former. Hospital managers should take measures to promote the sound interaction between the two so as to enhance the core competency of their hospitals.

Object To analyse genetic polymorphism in DNA level of three species and determine them in molecular level by using of the optimization of Citrus medica cv. sarcodactylis (Noot.) Swingle RAPD reaction.Methods RAPD reactions were performed under the following conditions:template DNA 10～100 ng/?L, 3.0～5.0 mmol/L MgCl 2, 200 ?mol/L dNTP,0.2 ?mol/L 10 mer Primer, lunit Taq Polymerase/25 ?L reaction volume.Results Twelve efficient and stable primers were selected from 38 primers. Phenograms were constructed by using genetic distance UPGMA method. Based on the results of the RAPD analysis and on a review of morphological characterisitic, C. medica cv. sarcodactylis species BAIHUAQINGPI could be used as BAIHUABAIPI in three species, there were some special amplified bands in every RAPD reactions from different species. Conclusion This method could serve as an easy and highly efficient method for C. medica cv. sarcodactylis genetic polymorphism and molecular identification of species.

OBJECTIVETo determine the compound Daqiqi decoction( CDQD) combined cisplatin plays on the cell apoptosis of subcutaneous transplanted ovarian cancer in nude mice, to provide theory evidence for clinical treatment.

METHODMaking the models of subcutaneous transplanted ovarian cancer in nude mice, and divide the 40 mice with tumor into 5 groups (n = 8), the model control group, CDQD low dosed group, CDQD high dosed group, cisplatin group, cisplatin combined CDQD group, killing all the mice after 3 weeks' treatment and stripping tumors. Measure the volume and weight of the tumor and calculate tumor growth curve damps, the inhibition rate. Examining the expression of the Bcl-2(B-cell leukemia /lymphoma 2) and Bax (Bcl-2 associated x protein) mRNA and protein by the RT-PCR and the Western blot.

RESULT(O)The tumor weight shows that there was certain lighter effect in each CDQD group, and compared with cisplatin groups has no statistical significance, the cisplatin combined CDQD group is obviously lighter than that of the other group(P <0.01). The tumor growth curve damps shows that compared with model control group, the treatment group tumors had some extent narrowing (P < 0.01). (2) RT-PCR results: Bax (Bcl-2 associated x protein) mRNA expression shows that compared with model control group, the treatment group has increased (P < 0.01), and the cisplatin combined CDQD group compared with the other group is the highest, there was significant difference with the rest of the treatment group (P < 0.01). In the Bcl-2 mRNA express lowest in cisplatin combined CDQD group (P < 0.01), there has no difference between CDQD high dose group and cisplatin group. (Western blot shows: compared with model control group, the Bax protein of treatment group has increased expression (P < 0.01), the expression of Bax protein in cisplatin combined CDQD group is the highest(P < 0.01). There has no difference between CDQD high dose group and cisplatin group. The Bcl-2 protein expression of the cisplatin combined CDQD group is the lowest (P < 0.01), there has no difference between CDQD high dose group and cisplatin group.

CONCLUSIONThe effect of CDQD on subcutaneous transplantation ovarian tumor has promoting apoptosis function, its mechanism may be related to downgrade the Bcl-2 expression, higher expression of bax, stimulation on the apoptosis of tumor cells; cisplatin combined CDQD have synergistic effect.

Objective To analyze the clinical characteristics of dengue fever (DF) in Guangzhou Higher Education Mega Center (HEMC) in the year of 2014. Methods A retrospective analysis was carried out in the clinical data of 487 cases of DF patients. Results The incidence of DF accounted for 27.18% ( 527/1939) of the total emergeney fever cases. In 487 DF cases with detailed data, 261 were male, and 226 were female; 312 were young aged, 88 were middle aged, and 87 were old aged. For the systemic symptoms, fever accounted for 87.5%, headache 48.3%, and muscular soreness 47.6%. Cough ( 16.6%) , pharynx pain ( 16.8%) and running nose ( 10.9%) were common in respiratory symptoms; poor appetite ( 14.4%) and nausea ( 10.3%) were common in gastrointestinal symptoms. The abnormal laboratory parameters were mainly shown as WBC count ( 48.25%) and PLT count ( 41.68%) , following by creatine kinase ( CK, 39.49%) , aspartate aminotransferase ( AST, 34.12%) , and lactate dehydrogenase ( LDH, 31.96%) . Less cases had abnormal renal function. The distribution of Chinese medical syndrome types was shown as damp-heat blockage (65.7%), syndrome involving Weifen and Qifen simultaneously (23.6%), and Qi-yin deficiency (10.7%). Conclusion In the year of 2014, DF in Guangzhou HEMC occurred mainly among the youth people, the incidence of male DF was similar to that of the female DF, and DF cases usually have the primary symptoms of fever, aversion to cold, headache and muscular soreness. Bleeding is seldom seen in the DF patients, a few cases are complicated with the damage in the blood, liver and myocardium, and most of them have good prognosis.

Objective To optimize the preparation technology ofCangai volatile oil dextrin inclusion compound/ in situ nasal thermosensitive gel by the central composite design-response surface method.Methods In the design, the investigation factors were the amounts of poloxamer 407 and poloxamer 188, and the evaluation index was the gel temperature.

The effects of amino acid electuary on experimental liver fibrosis in rats with chronic liver injury induced by CCI4 were studied. The results showed that the electuary could prevent the decrease in body weight and food intake, reduce the levels of serum glutamic-pyruvic transaminase activities, elevate contents of total serum protein and serum albumin, normalize the serum ratio of BCAA to AAA and disordered amino acid pattern and suppress degeneration, necrosis and fibrosis of liver tissues in rats with chromc liver injury. These results indicate that the amino acid electuary has beneficial effects in prevention and treatment of liver fibrosis.

The effects of amino acid electuary (Ganan Elemental Granules) on experimental acute hepatic failure induced by D-galactosamine in rats were studied.

Objective To investigate the expression level and clinical significance of long non-coding RNA(LncRNA) growth arrest specific gene-antisense 1(GAS8-AS1) in papillary thyroid microcarcinoma(PTMC) patients. Methods We investigated the expression profile of GAS8-AS1 in tissue samples of patients with PTMC as well as nodular goiter(NG) by quantitative real-time polymerase chain reaction(RT-qPCR). Results GAS8-AS1 in cancer tissue was down-regulated in PTMC patients compared with adjacent thyroid tissue and NG samples(P<0.05). Lower level of GAS8-AS1 was also correlated with central cervical lymph node metastasis(CLNM, P<0.05). The area under the ROC curve for GAS8-AS1 was up to 0.717 3 in CLNM prediction(P<0.05). Conclusion GAS8-AS1 may act as a potential biomarker for PTC diagnosis and CLNM prediction.
